It was only a few weeks ago that Moustache introduced the Dimanche 28, their first electric road bike. To make the most of the existing frame concept, the French brand just built a brand-new eGravel bike around it. The new Dimanche 29 is available in two different spec options, both intended for off-road use. If you want more details about the French e-platform, read our first test of the Dimanche 28 here. The Moustache Dimanche also cuts a good figure for bikepacking. You want to know everything about bikepacking and bikes, gear, route planning and accommodation?

The concept behind the Moustache Dimanche 29

Unlike the Dimanche 28, which features a Bosch Active Line system, the Moustache Dimanche 29 is powered by a third-generation Bosch Performance Line motor. Moustache’s promise: with its 500 Wh Powerpack battery, 63 Nm of torque and a maximum support of up to 300 %, the motor provides a healthy portion of extra off-road power and takes the edge off long challenging gravel tours, thus allowing for a less strenuous, more fun riding experience. Via the Kiox or Purion display (depending on the bike’s spec), you can adjust the strength of the “artificial tailwind” by shifting between the Eco, Tour, Sport and Turbo modes, up to a maximum speed of 25 km/h. Once you exceed this limit, however, the law requires you to use your own leg strength. Thanks to the fine modulation of the motor, the transition at the 25 km/h threshold should be particularly smooth.

The carbon fork and the endurance-inspired geometry of the aluminium frame are designed to interact as a reliable unit, one that wants to inspire confidence whilst providing maximum riding fun. The mounting points on the frame and fork accommodate a front pannier-rack and a mudguard respectively. With a tire clearance of up to 700 x 50C (knobbly tires) and the 180 mm front / 160 rear rotor-combo, Moustache wants to meet the requirements of a wide range of different gravel riders whilst giving them plenty of room for personal adaptations. Thanks to the Bosch Performance Line mid-drive motor, the Dimanche 29 is compatible with a number of different wheel combinations.

Besides focusing on the user-friendliness and reliability of their products, Moustache really care about ergonomics and the safety of their customers. As a result, the riding position of the Dimanche is a lot more upright than on most conventional road bikes – the low saddle height, high front-end and compact frame dimensions are mainly responsible for this. In addition, Moustache employs a number of features such as the handlebars with a 16° flare and wide 50 mm tires to complement the compliant seat stays and achieve the highest possible level of comfort. Furthermore, the long 455 mm-long chainstays should guarantee an even smoother ride.

Moustache Dimanche 29 – first riding impressions

We’ve already had the opportunity to test the Dimanche 29 at the official launch event for the Dimanche 28 eRace bike – you can read all about it here! The spec of our test bike, however, is not consistent with the final production model. We tested the Dimanche on Julien Absalon’s very own training grounds, a magnificent sequence of wide gravel tracks and technical trails with mixed terrain – something we’d love to have on our own doorstep. Whilst the Dimanche inspires a great deal of confidence, it’s still nimble enough to master tight slow-speed corners, even despite its long 455 mm chainstays. The bike literally begs you to have fun and inspires such a high level of confidence that even smaller jumps are not a problem.

The wide bars and upright, centred riding position ensure a balanced weight distribution and provide good control even on rough terrain. While the aluminium frame and the 31.6mm aluminium seatpost only generate little compliance, the wide 700 x 50C Maxxis Rambler tires with tubeless setup efficiently absorb impacts. Whilst this type of comfort doesn’t have any damping qualities, in combination with the lively handling it provides a playful character and a lot of off-road fun. The Maxxis Rambler tires also impress with outstanding grip. You can find a comprehensive test of the tires here. Due to the damping effect of the carbon fork, the front-end feels a lot smoother than the rear-end.

The disc brakes and 180 mm front-rotor both suit and complement the good-natured character of the Dimanche 29. Even on steep terrain and long downhill sections, the big brake-rotor provides for optimum heat dissipation and makes for an overall safer, more enjoyable ride. Talking of riding fun: once you cross the 25 km/h threshold, the party is over. On rough terrain especially, you’ll need a lot more strength to move the bike without the help of the motor. A more detailed test of the bike will shed some light on these and many other aspects. Soon you’ll be able to find out more about the Dimanche 29 on our website.


With its clever spec and well thought-out geometry, the Moustache Dimanche 29 is a fun off-road gravel rig. The large contact surface of the tires generates lots of traction, which, in combination with the flared handlebars and central riding position, inspires tons of confidence and conveys a high degree of safety. Once you cross the dreaded 25 km/h threshold, however, the off-road enthusiasm will quickly dwindle. If you’re looking for a trusted companion for your exciting trail adventures or simply want some peace of mind on your next long gravel tour, the Dimanche 29 might just be what you’re looking for.
